Soak rolls in cold water. Peel and finely chop the onion. Squeeze out the bread roll thoroughly. Pluck the thyme leaves from the stalks. Knead minced meat, roll and egg.
Add thyme and season with salt and pepper. Form approx. 12 small meatballs from the minced mass. Heat the oil and fry the meatballs for about 10 minutes, turning them over. Mustard tastes good with it
